Aengus of Sredkistrasse brought my attention to this very novel site (hours of fun I say):
Back when I was in school, I’d have to wait an hour or so before being collected by one of my parents on the way home from work. In this time, I’d usually spend the time hanging about with what friends would loiter a bit longer after school, but occasionally I’d go find an empty classroom and get some work done.
There was one chap, a right arsehole if truth be told, who’d come around occasionally, listening to the cops and other emergency services on his radio scanner. I’d always wanted to get one, but they were prohibitively expensive, and, anyhow, at the time I lived in the middle of nowhere, so it wouldn’t have served much use.
Now, thanks to the wonders of the internet, I can finally live out these past dreams. On scanamerica.us you can listen in on the emergency services in some counties of some states.
